WHlFFLETREE-HOOK.

SPECIFICATION forming-part of Letters Patent No. 397,201, dated February5, 1889.

Application filed March 10, 1888. Serial No. 266,914. (No model.) i

To all whom it may concern:

Be it known that I, SAMUEL O. NICHOLS, a resident of and citizen of Weare, in the county of Hillsborough and State of New Hampshire, haveinvented a new and useful Improvement in \Vhiiiietree-llooks, of whichthe following, taken in connection with the accompanying drawings, is aspecification.

My invention relates to in'iprovcments in whifiietree-hooks; and itconsists, mainly, of an ordinary whilti etree-hook with a pin or boltwhich slides in a hole made in the whittletree exactly opposite the endof the hook, the pin or bolt being attached to a strap-spring on theback of the whitfletree, the hook and pin forming, when in place, acompletely-. closed and safe link.

The construction and operation of my in vention are described asfollows:

Figure 1. represents a front view of my hook attached to a whitlletree,the hook being closed. Fig. 2 is the same view, the hook being thrownopen. Fig. 3 represents the spring which holds the sliding pin orbolt din place, and Fig. -:t represents the sliding bolt or pin d.

The pin d is of the same diameter as the end of the hook c, and the endof the pin and the end of the hook are made to fit exactly. The spring Cis forked at the movable end, as at f, and the pin d is slotted verynear the head on two sides, as at g. In making, the

spring (J, which in Fig. 1 is in view, should be let into the wood sothat when in place its face is flush with the surface of the wood.

in Fig. 2, and is pressed forward and held in 40 place by the spring.

The advantages of my hook are obvious. It holds the tug or trace so thatit cannot become detached or unhooked accidentally; nor

will the hook catch the reins, the horses tail,

bushes, brush, or sticks. The sliding pin be ing of the same sizethroughout as the end of the hook, and the spring which holds it being011 the back side of the whiflletree and let into the wood or pressedclosely against it, the pin cannot be shoved back so as to open the hookwhen the WllliIlGllQG is dragged over the ground.

Having described my invention, I claim as new and desire to secure byLetters Patent The whiffletree-hook herein described, con sisting of thehook E, the movable pin 01, in combination with the strap-spring 0,constructed in the manner and for the purpose specified.

In testimony whereof I have signed my name to this specification, in thepresence of two snlr scribing witnesses, on this 3d day of March, A. D.1888.

SAMUEL O. NICHOLS.
